Embodiment

[0102] The process of the printing multimedia system processing method is described in detail below in conjunction with Fig. 1:

[0103] The implementation method of the multimedia printing system for low-resolution printing equipment is composed of a multimedia data input part 100 , a multimedia editing part 200 and a multimedia data output part 300 .

[0104] The multimedia data input part 100 is shown in Figure 13; it is composed of a DTP data reading unit, an outline extraction unit and a color adjustment unit. The specific operation steps of the page design part 100 are as follows:

[0105] (1) Read the DTP data unit, read the DTP data to the screen, and convert the DTP data to C, M, Y, K four colors. It can also be the DTP printing page design data produced by this unit, that is, the multimedia data input part 100 is a DTP printing page design system.

[0106] (2) Determining the information embedded field unit, aiming at the different content of each printed image tha...

Abstract

The invention discloses a method for forming new type mesh code for identification, an information embedded method for multimedia print, and a method for constituting multimedia print system. The said new type mesh code uses following parts: different geometric distributions including displacement, direction, and shape of mesh point to record information directly; different physical distributions including phase modulation of 2D image, propagation direction of mesh point to record information directly; and method for partitioning mesh points on mesh screen. Features are: even gray scale of mesh point, small size of mesh point, and large capacity of information. The small size of mesh point is in favor of recognizing codes, and suitable to embed information to any printing image as well as gives small influence on image quality after information is embedded.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to a method for realizing a multimedia printing system used in low-resolution printing equipment. Background technique [0002] Multimedia printing is another revolution in today's printing industry. Recently, the patents related to printing multimedia in Japan have been disclosed one after another. As early as the 1990s, in Japan, someone proposed "reference sound output device [reference sound output device] (patent publication 8-202252)]", "books that can produce sound [Sound の 出る本 (Patent Publication 9-218695)]". The above two patents propose to print any number of identification marks on the book, and match the mark to the pre-recorded sound in the semiconductor memory. After reading the mark, the pre-recorded sound can be played automatically, so as to realize the effect of a book with sound . In the realization of books that can produce sound, this patent does not pro...
